help please i'm stuck at this point of cracking

i've installed backtrack 3 in a vmware machine also i'm using a tp link adapter for to do it
this is the model tl- wn422g 54 mbps high gain
i have wifi internet
i can surf the internet (inside backtrack)
but the problem starts when i type in the kernel console
nothing appears in interface channel etc
then i try iw config and also nothing detects and it's frustrating because i'm connected to the internet
please help me to solve my problem
